Your Money or Your Life
by Joe Dominguez and Vicki Robin
This is a very good book on Personal Finance.
It teaches you how to reach financial independance and improve your relationship with money.
Many people are in bad shape financially due to ignorance. That is why we really need to learn about personal finance.
I strongly recommend you to read this book. It has helped me financially and now, thanks to the book, I am planning my retirement in 5 to 15 years time. 
wish me luck.
Remember, this book is not teaching you how to become a rich guy nor speculating in stock market.
It guides you to gain a better relationship with money and pave way to financial freedom. You will know what you trully need to buy with money, what is a waste of money and so on by reading this wonderful book.
